This invention relates to gun sights and particularly to adjustable rearsights especially of the peep type.

Objects of the invention include the provision of a rear gun sighthaving extremely easily adjustable means for varying the elevation, saidsight being simple in nature and inexpensive to manufacture, without,however, losing effectiveness, accuracy, or ease of manipulation.

Other objects and advantages will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is atop plan view of the new gun sight, parts being in section;

Fig. 2 is a vertical cross section longitudinally of the gun sight;

Fig. 3 is a view in side elevation thereof;

Fig. 4 is a view in side elevation of the adjustable spring strip;

Fig. 5 is a bottom plan view thereof, and

Fig. 6 is a rear elevational view of the sight looking in the directionof arrow 6 in Fig. 3.

The present gun sight may be attached to the receiver of the rifle orother weapon by any convenient or desired means, but in the presentinstance the securing means is shown as a keystone or dovetailed baseIII which fits into a complementary slot arranged transversely of therifle barrel. The base I 0 is provided with a pair of parallelupstanding side walls I 2 and I4 which are triangular in form, havingtheir narrowest edge portions forwardly relative to the base l0 so thata wide edge is located to the rear as at l6, for purposes to bedescribed. Side wall I2 is beveled off at its rear end as at l8 and inthe area of this bevel side wall I2 is engraved by markings 20indicating the elevation in yards. Also the rear ends of walls I2 and I4are correspondingly notched as at 22. A pin 24 is set into side walls l2and I4 adjacent the forward end of the sight, close to the upper surfaceof the base plate ID. A generally L-shaped spring strip 26 is providedwith eyes 28 which are hooked over the pin 24 so that the latter acts asa pintle to provide for a swinging movement of the spring arm 28thereabout, it being noted that the spring arm is positioned between thetwo walls l2 and l 4.

Spring arm 26 is provided with an upstanding foot 30 terminating in afinger grip 32 and at the angle forming the foot there are out outportions at 34 which easily provide for a slight bending of the foot 30relative to the leg of the spring upon manual manipulation of the fingergrip 32 towards the right in the drawing. The foot 30 is also providedwith a laterally extending element 36 which terminates in a bent ovepointer 38; and it will be noted in Fig. 1 that the pointer 38 isconfined to a position wherein it cannot extend beyond the outer surfaceof wall I 2 but still overlaps the beveled portion l8 of this wall. Thepointer 38, of course, indicates the range of the firearm by varyingelevations of the spring and it will be seen that the sight is set atyards in Fig. 3. The element 36 is depressed at 40 and a correspondingelement 42 without a pointer is similarly depressed at the other side ofthe spring foot 30 so that the depressions will snap into the notches 22at whatever elevation is selected to hold the sight in this position.The spring foot 30 is also provided with a vertical slot 44.

A special hollow screw 46 having a flange 48 extends thru slot 44 andprovides the peep sight. A hollow internally threaded nut 50 is used toclamp the Deep sight 46 to the spring foot 30 in the above manner asillustrated in Fig. 2. The peep sight 46 is adjustable vertically inslot 44 merely by loosening nut 50 and retightening the same wheredesired.

It is believed that the operation and adjustment of the device will beapparent from the above description when taken in conjunction with thedrawing, it being noted however that the side walls I2 provides a pairof shoulders at 52 which define upper and lower limits in conjunctionwith the pointer 38 to prevent disassembly or excess adjustment. Tochange the elevation, finger grip 32 merely needs to be pressed slightlyby the finger so as to swing the spring foot 30 away from rear edges l6,thereby disengaging the depressions in elements 36 and 42 from theirnotches, and then the sight may be adjusted by swinging the spring armon the pintle 24. The sight can be zeroized and the rifle can betargeted in by taking advantage of slot 44 and adjusting the peep sightrelative to the spring foot until proper shooting is obtained.

While a particular form of the invention has been illustrated anddescribed, it is to be understood that many modifications may be madetherein by any person skilled in the art without departing from thespirit oi the invention as expressed in the claims. Therefore, I do notwish to be limited to the particular construction shown, but havingfully described the invention and ascertained the manner in which thesame is to be performed, what is claimed and sought to be'secured byLetters Patent is:

1. As an article of manufacture, a base late adapted for attachment to afirearm, said base plate being provided with a pair of upwardlyextending side walls, said side walls having correspondin end edgesnotched, an arm swingably mounted in the device and having an angularend spring portion means on the latter cooperating with said notches forlatching the spring arm in various adjusted positions relative to thebase, and means in the spring arm providing a sight.

2. A gun sight comprising a support, means for securing the support to agun, apivot element on the support, a spring steel strip mounted toswing on the pivot element, an upstanding end portion on the strip,cooperating latching means on the support and sprin end portion forlocating the strip in adjusted positions relative to the former, 15

a sighting aperture through the'spring strip, said spring strip beingmanually adjustableby springing the same to disengage said latchingmeans.

3. A device of the class described a base plate, a pair of upwardlyextending walls on the base plate, a generally L-shaped spring armswingably mounted 'on the device, means resiliently latching the springarm in variable positions of adjustment thereon, a portion of saidspring arm extending upwardly, means forming "a slot in said portion, ahollow element forming a peepsight extending through said slot, andmeans adjustably securing said element in desired position in said slot.v
